The
version of this piece you are now hearing is being played with the
first two voices tuned in Harpway Flat and the third voice in Harpway
Sharp, so the key signature could either be displayed with three flats
or one sharp as shown.

Instructions for tuning:

Set top string to C# (A 415) to
minimize danger of breaking strings

2nd string: A#

3nd string: F#

4th string: C#

5th sring: F#

Lowest string: C#

To tune to Harpway Flat (defhf) just
lower the the 2nd string to A natural.If
you would like to try this piece out without retuning your instrument

This round will work with three
tenors or any combination of bass and treble viols.If you would like to working
up your own version using tenors in combination with other viols here's
